15.6.3.2 ML-Series Card Ether Ports Utilization Window

The Ether Ports Utilization window shows the percentage of Tx and Rx line bandwidth used by the
Ethernet ports during consecutive time segments. The Utilization window provides an Interval
drop-down list that enables you to set time intervals of 1 minute, 15 minutes, 1 hour, and 1 day. Line
utilization is calculated with the following formulas:
Rx = (inOctets + inPkts * 20) * 8 / 100% interval * maxBaseRate
Tx = (outOctets + outPkts * 20) * 8 / 100% interval * maxBaseRate
The interval is defined in seconds. The maxBaseRate is defined by raw bits per second in one direction
for the Ethernet port (that is, 1 Gbps). The maxBaseRate for ML-Series Ethernet cards is shown in
Table
Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.

ML-Series Ether Ports PM Parameters (continued)
Definition
1
The total number of good packets received that were directed to a
multicast address. Note that this number does not include packets directed
to the broadcast address.
The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either a bad
FCS with an integral number of octets (FCS Error) or a bad FCS with a
nonintegral number of octets (Alignment Error).
1
The total number of octets of data (including those in bad packets)
received on the network (excluding framing bits but including FCS octets.
Number of transmit packets that are collisions; the port and the attached
device transmitting at the same time caused collisions.
The total number of packets received that had a length (excluding framing
bits, but including FCS octets) of between 64 and 1518 octets, inclusive,
but had either a bad FCS with an integral number of octets (FCS Error) or
a bad FCS with a nonintegral number of octets (Alignment Error).
Number of received frames dropped at the port level.
2
Number of received Ethernet 802.3z pause frames.
Number of received oversized packages that are dropped.
2
Number of received frames that are too long. The maximum is the
2
programmed max frame size (for virtual SAN [VSAN] support); if the
maximum frame size is set to default, then the maximum is a 2112 byte
payload plus the 36 byte header, which is a total of 2148 bytes.
